COP-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 772,603, dated October18, 1904.

7 Application filed January 19, 1908. Serial No. 139,576. (No model.)

To all whom it may concern:

Be it known that we, J OHN H. BENTLEY and WILLIAM GREGORY, citizens ofthe United States, residing at Paterson, in the county of Passaic andState of New J ersey, have invented certain new and useful Improvementsin Cop-Winding Machines, of which the follow I mechanism for startingthe spindle in its upward movement at the'beginning of the formation ofthe cop. While our machine applies to cop-winding generally, it isespecially designed for winding a hollow cylindrical cop with a roundedor somewhat-conical nose and base, from which in use the thread can bedrawn either from the interior or exterior,

but preferably from the interior.

The object of our invention is to provide a machine that will produceatubeless cop adapted for use in shuttles for weaving purposes and whichwill so wind the cop as to permit the thread to be delivered from eitherthe interior or exterior of the cop with evenness and regularity when itis carried through the shed by the shuttle in the process of weaving.

The further object of our invention is to provide such a machine with aloosely-mounted cup or thimble to surround that portion of the spindlewhereon the cop is formed and having a hollow conical-shaped interior.

A further object of our invention is to provide in such a machine meansto start the spindle in its vertical movement at the time that the copis beginning to be formed; and a further object of our invention is toprovide the clutching mechanism with an adjustable friction devicethatwill causethe spindle to revolve gradually for a period beforethemain clutching devices are engaged to rotate the spindle at itsusualspeed; and a still further object of our invention is to provideautomatic means for disengaging the clutch devices to stop the :spindleautomatically upon the breakingof a threadand for withdrawing thespindle from the cop when it is finished.

In theaccompanying drawings like characters of reference indicate likeparts.

Figure 1 is an end 'view of a portion of a machine embodying ourimprovements. 2 is a side elevation of same, showing our compound clutchdevice in section. Fig. 3 is a plan view of a portion of a machine,showing a method of imparting a vertical movement to the spindle fromthe main shaft. Fig. 4 is a section through our cop-forming cup, showingthe method of loosely mounting the same in the upper table of themachine. Fig. 5

shows detail views of the automatic spindleelevating device, both insection and in elevation, the section being on the line 2 z, the devicebeing out of operative engagement. Fig. 6 shows detail views the same asFig. 5, with the exception that the swinging pawl and ratchet of thespindle-elevating device are in operative engagement. Fig. 7 is a viewsimilar to Fig. 1, but enlarged, and showing a mechanism for driving thespindles and Fig. 8 is a plan view of one set of four spindles, showingthe mechanism for driving the same.

The operating mechanism connecting the shaft 1 with the gearing 31consists of a mitergear a, which is secured to said shaft 1 and mesheswith a miter-gear b, which is secured with the gearing 31. The shaft 6is mounted Fig.

in the support or bearingd, and to the shaft c is secured the spur-gearc and the mitergear 6. The bearing d is secured to the frame 26. Thespur-gears 31 are secured to the spindles 11, which are operated fromthe main shaft 1 through the above-described operative connections.

Power is communicated to the main driving-shaft 1.0f the machine by beltor pulley or in any other suitable manner. A worm 2 is secured to theshaft 1 and engages a wormgear 3, secured on shaft 4:, which is mountedat right angles to the main shaft.

end of the shaft 4 are secured worms 5, which engage and turn worm-gears6, secured to the On each shafts 7 7 which are mounted parallel to eachother on either side of the machine and at right angles to the shaft 1.

On the shafts? 7 are secured ratchet-wheels 8, one for each spindle onthe machine, and these ratchets 8, turning with the shafts '7, areadapted to engage the swinging pawls 13 when said pawls are swung in thedirection of the ratchet by the arm 10, which is secured to theconnecting-rod 9 upon the up ward movement of the said rod.

The swinging pawl 13 is suitably mounted in the fixed bracket 12,secured to the spindle 11. As illustrated in Figs. 5 and 6, the turningof the ratchet in engagement with the swinging pawl 13 causes thespindle to rise until the pawl 13 has been carried to a point beyond theengagement of the ratchet. This elevating of the spindles by means ofthe ratchet 8 and swinging pawl 13 is gradual and continuous while itlasts and takes place at the beginning of the formation of the cop, asit will hereinafter more fully appear, and prevents the bunching of thethread, which is otherwise liable to occur, and by providing for thedistribution of the thread on the rising spindleinsuresagood foundationfor the commencement of the cop-building process.

The bracket 12, which is secured to the spindle 11 and in which theswinging pawl 13 is mounted, has a forked end passing on either side ofthe connecting-rod 9, and from the top of the bracket 12 passes a chainor cord 14, one end of which is secured to said bracket 12, and thenceover a sheave or roller 15, which is secured to said connecting-rod 9,and a weight 16 is secured to the other end of said chain or cord. Onthe upper table 17 of the machine is secured a tilting block 19 on abase 18.

The tilting block is provided with a handle 19 and the usual arm 20.

The tilting block 19 is pivotally secured to the stand 18, and theconnecting-rod 9 is pivotally connected with the rear upper portion ofthe tilting block 19, as is indicated by 21. WVhen the tilting block 19is tipped back, as indicated to the right in Fig. 2, the connecting-rod9 is lowered and our compound clutch device is disengaged, so that thespindle 11 is not rotated; but when the tilting block 19 is down andforward, as is indicated to the left in Fig. 2, the connecting-rod .9 isdrawn up in Fig. 2, when the cop is finished and the tilting block 19 istipped back, disengaging the clutch mechanism and stopping the operationof the spindle.

Owing to the point of connection of the rod 9 and the tilting block 19the pressure of the friction-cone 59 of the rising spindlel 1 againstthe friction-cone 58 on the rod 9 causes the tilting block 19 to betipped back, as shown on the right in upper portion of Fig. 2, and theweight 16 aids in the tipping of the tilting block and the drawing downof the rod 9.

The mere engagement of the friction-cone 59 with the friction-cone 58 isin itself suilicient to accomplish the tipping of the tilting block, andthe weight 16 may or may not be used. Said cup 22 is provided with avertical slot 8 in one side thereof and on two sides with a recess, intowhich recesses 2a the arms of the plate 23 are adapted to it loosely.The opening in the plate 23 is the shape of a horseshoe, and the plateitself is secured to the stand 18. The cup is capable of a slight motionor movement in any direction and is held in place in the plate 23 by thespindle 11, which passes therethrough.

It is not deemed necessary in this application to show how the cop isformed by the traverse of a vibrating distributing device which conveysthe thread up and down through the said slot .v as the thread is beingwound upon the spindle 11.

The cup 22, as shown in Fig. 4, has an opening therethrough to receivethe upper end of the spindle 11. The upper portion 55 of said opening islarger than the opening in the lower portion of the cup. The opening inthe lowerportion is cone-shaped, and the opening in the upper portion isbell-shaped, as shown in Fig. 4, and where the bell-shaped portion meetsthe lower cone-shaped portion 56 an annular ridge 57 is formed, which issmaller in circumference than any other portion of the opening throughthe cup, but which allows to a certain extent for any vibration of thespindle. This movability of the cup aids in the formation of the cop andallows for a more perfect adjustability of the cup to the cop during thewinding process, and the rounded conicalshaped shoulder 25 makes themovement of the cup 22 free. On the lower su morting-table 26 of ourmachine is secured the rail 27, which carries our auxiliary clutch andwhich is provided with the cylindrical sleeve 27. A sleeve 28, having anannular flange 29 at its lower end, is secured in the sleeve 27 andthrough said inner sleeve 28 the spindle 11 passes and turns. Betweenthe inner sleeve 28 and the outer sleeve 27 is a loose sleeve 30,adapted to be rotated around the inner fixed sleeve 28 above the annularflange 29. Said intermediate sleeve 30 has secured to it a gear 31,which is driven from the main shaft 1. On

the lower portion of the loose sleeve 30 and integral therewith is ahollow cylindrical portion 32, having on its inner side twooppositely-located lugs 33, which forms a portion of our compoundclutch. i

The lower portion of our clutch consists of the plate 3 1, having anextended hub with a central opening therethrough provided with a featheror key adapted to slide in a key-seat or longitudinal slot in thespindle which passes through the central opening in the plate 34;, asindicated at 36 in Fig. 2. On the "upper surface of the plate 3 1 aretwo lugs or jaws 35, adapted to engage the corresponding lugs 33 in theupper clutch member.- The spindle 11 projects below the bottom of theclutch member 34 and through an opening in the arm 37, which is securedto the lower end of the connecting-rod 9, so that'when the tilting block19 is tripped and falls back, as is shown to the right in Fig.2, theconnectingrod 9 is lowered, the lower clutch member drops out ofengagement with the upper clutch member and rests on a lever;arm' 37,through which the spindle 11 passes.

I reverse is the case when the tilting block is Saidspring-band extendsa distance above" member is rotated.

' too great a strain upon the mechanism and upon the threads. Wetherefore-employ an auxiliary clutch member to start the spindle in itsrotary movement at the time the cop is begining to'be formed and for ashort'period before the lugs of the upper and lower clutch members areengaged, which will rotate the spindle at a lower speed, and thus avoidthe breaking of the thread. This auxiliary clutch member consists oftheadjustable spring-band 38, which is secured to an annular shou'lderonthe clutch member 34 on pins which pass into longitudinal openings 10 inthe said bands, the ends of said band being adapted to be drawn togetherby the tightening and loosening device 39 to regulate the friction orgrip of the band on and around the outer surface of the hollowcylindrical portion 32 of the sleeve 30.

the lugs 35 on the clutch member 34,and by virtue thereof the frictionof the spring-band,- with the sleeve 30, turns the lower clutch member34: until the lugs 33 and 35 become engaged, so that the formation ofthe cop has been well begun before the spindle is rotated at full'speed.

VV'e employ a hand-operated device which is connected with the spindlefor the purpose 11 is secured a friction-cone 59.

The

'of doffing the cop. By pressing on the handlever of the device thespindle is forced downwardly out of the cop when the cop is completed,and the thread first wound around the spindle at thecommencement of theformation of the cop is the delivery end of the thread when the cop isplaced in the shuttle for weaving purposes. It is thus obvious that thethread is delivered from the interior of the cop. On the connecting-rod9 is secured a friction-cone 58, and on'the spindle When the cop iscompletely formed on the spindle 11 in the cup 22, the spindle 11 iselevated to such an extent that the friction-cone 59 engages thefriction-cone 58 on the rod 9,

and the lateral pressure thus produced trips the tilting block 19, thuslowering the rod 9 and the clutch-support connected to the lower endthereof, disengaging the clutch, and stopping the rotation of thespindle '11. (See right-hand portion of Fig. 2 in the drawings.)
